Summary:A data processing block comprises: a syndrome calculation unit configured to generate odd number syndrome values from a received code word; an ELP solver configured to generate even number syndrome values based on the odd number syndrome values in a first mode, and to generate an error position polynomial expression based on the odd number syndrome values and the even number syndrome values in a second mode; and a Ziehen search unit configured to generate a solution for the error position polynomial expression. 데이터 처리 블록은 수신된 코드워드로부터 홀수 신드롬 값들을 생성하도록 구성된 신드롬 연산 유닛, 제1 모드에서 상기 홀수 신드롬 값들에 근거하여 짝수 신드롬 값들을 생성하도록 구성되고, 제2 모드에서 상기 홀수 신드롬 값들 및 상기 짝수 신드롬 값들에 근거하여 에러 위치 다항식을 생성하도록 구성된 ELP 솔버 및 상기 에러 위치 다항식의 해를 생성하도록 구성된 치엔 서치 유닛을 포함한다.
